The difference between these two lines...
*test*
*test* here
...is that the former has emphasization at line's end, and the latter
does not.  Emphasization of the former does not occur, but it does occur
for the latter.  It seems to me that this worked long ago, but has not
worked properly for a long time -- I can't even guess when it stopped
working, but it was probably over a year ago.

This is driven by gnus-emphasize-whitespace-regexp (defvar'd in
gnus-art.el) and gnus-put-overlay-excluding-newlines and
gnus-put-text-property-excluding-newlines (defun'd in gnus-util.el).
Any ideas for what has gone wrong with this?
